Toronto, Canada – August 14, 2012 – Goldstar Minerals Inc. (“Goldstar” or the “Company”) (TSX-V: GDM) is pleased to announce that it has entered into a purchase and sale agreement with Ressources Maxima Inc. (“Maxima”) to acquire from Maxima its 100% interest in 64 claims covering approximately 3,500 hectares (35 km2), located in Mont-Laurier, Quebec (the “Brockaby Property”). In consideration for this interest, Goldstar has agreed to pay Maxima a cash payment in the amount of $6,784 and issue 100,000 common shares of Goldstar. In the event that the Property attains commercial production, the Company shall pay Maxima an additional cash fee of $500,000.

Closing of the acquisition remains subject to the completion of successful due diligence, to the sole discretion of the Company and upon receipt of all necessary Board and regulatory approvals, including the approval of the TSX Venture Exchange.

In addition, the Company is pleased to announce that it has acquired, through staking, a 100% interest in 139 claims covering approximately 7,650 hectares (77 km2). These claims are contiguous to the Brockaby Property, and upon completion of the acquisition, the Company will maintain a 100% interest in approximately 203 mineral claims comprising 11,150 hectares. The Brockaby Tungsten Property is located roughly 75 km northeast of the town of Mont-Laurier, Quebec and access is excellent through a network of logging roads. The property is underlain by marble and paragneiss sequences in contact with late stage and small size granite intrusions, favourable for skarn-type mineralizations as reported in 2007 by Suzy Nantel who mapped the area for the Ministère des Ressources naturelles et de la Faune du Québec (“MRNF”). Stream sediment samples collected by the MRNF in the past also yielded many anomalous tungsten values, along the granite – marble contact, again very typical of skarn-type mineralizations. Goldstar Minerals plans a detailed geochemical soil survey and an airborne magnetic survey in the coming weeks in order to define diamond drill targets.
